ORGAN.

SPECIFICATION forming part of Letters Patent No. 598,311, dated February1, 1898.

Application filed April 2 9, 1897.

T0 aZZ whom it may concern:

Be .it known that I, VICTOR ANDERSON, a citizen of the United States ofAmerica, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Organs,of which the following is a specification.

My invention relates to certain improvements in organs, and moreparticularly to that class of organs in which a great number of pipes isused. These pipes are ordinarily connected with a wind-chest whichreceives a supply of compressed air from a bellows or other source, andwhen they get out of order it is an exceedingly difficult operation torepair the injury. To obviate this difficulty, I have devised an organin which the windohest for each series of pipes is separate and easilyremovable, so that when an injury in a certain part is found thatwind-chest, together with its series of wind-pipes, may be removed forrepair without disturbing the others.

The invention is fully described in this specification and clearlyillustrated in the accompanying drawings, in which- Figure l is a planview of my preferred construction. Fig. 2 is a vertical cross-section inline 2 2, Fig. 1. Fig. 3 is a longitudinal section of one of thewind-chests upon an enlarged scale, the plane of section being 3 3, Fig.4. Fig. 4 is an enlarged cross-section of one of the wind-chests, theplane of section being a 4, Fig. 1. Fig. 5 is an under plan of adiaphragm used in this organ; and Fig. 6 is a section in line 6 6, Fig.5.

Referring to the drawings, and especially to Figs. 1 and 2, a series oflongitudinallyextending rails or beams are seen at A and are adapted tosupport the wind-chests B. As shown, these wind-chests rest between thebeams A and are provided on either side with angle-irons b, by means ofwhich they are seated upon the beams. At or near the ends of the beamsare cross-pieces a, adapted to serve as guides or stops to retain theWindchests in place and thereby insure the perfoot operation of thediiferent part-s.

Inasmuch as all of the wind-chests are alike I shall proceed to describeone of them, such description evidently pertaining to them all.

The framework of the wind-chest is com- Serial No. 634,328. (No model.)

posed of a comparatively wide strip Z), (see Figs. 3 and 4,) a narrowerstrip b secured upon the lower side of the strip Z), and a comparativelythin strip b secured upon the outside of the strip 12 and connected withthe upper edge of the strip 1) by a strip b These strips are glued orotherwise securely fastened together and form the walls of the chamberB, extending the entire length thereof. End pieces 6 are secured at theends to completely inclose the chamber. A pipe B (see Fig. 3) connectsthe wind-chest with the bellows of the organ, which may be of any of thewellknown kinds used in organs of this class and adapted to supply thewind-chest with a supply of air.

The wind-chest is connected with a series of pipes O, in which thedifferent notes are produced, these pipes being arranged along the topof the strip 1) and opening into ducts b formed in said strip. (See Fig.4..) These ducts extend into the strip b and open out into the chamberB, their orifices Z2 being closed by valves D.

In organs of this class the pipes are so arranged and operated thatseveral of the same pitch are put in communication with the compressedair simultaneously by the operation of one key or pedal. In the devicehere shown 1 in such a manner as to be operated simultaneously. Thevalves D above referred to are provided for each duct which leads tothese pipes and are hinged to the strip 19 in any suitable manner. Theyare operated by means of stems d, extending through openings in thestrip b the valves being provided with pins d, resting in eyes (Z in thestems. Near the bottom the stems are secured to diaphragms D by means ofcollars d" and shoulders d upon the stems, (see Fig. 6,) the diaphragmsbeing held firmly between the shoulders and collars. Rings D areprovided for clamping the diaphragms to the strip W, said rings havingears d through which screws are passed to secure the rings to the strip.Inasmuch as the wind-chest when in use is always full of air which isfree to circulate around the stems d and press upon the dia phragm thevalves are automatically kept closed except when opened by the operator.I have provided bell-crank levers E to open the valves, they beingpivoted upon brackets c secured to the beams A. The arms 6 of thesebell-cranks rest against the lower ends of the stems d, the other armsin each transverse series being connected by a bar or rod 6, extendingto the key-operating mechanism. As shown in Fig. 1, one of these rods isprovided for each transverse series of valvestems, each rod workingindependently of the other. By the use of the stops a the windchests maybe put in the proper position, so that the stems cl will comeimmediately above the bell-crank levers E, which is necessary to theproper working of the organ.

From the above it will be seen that when an accident happens to any ofthe wind-chests, pipes, or other working parts the wind-chest at thatpoint may be easily removed and the injury repaired.

I claim as new and desire to secure by Letters Patent- 1. In an organ,the combination with the removable wind-chest, B, having the air-ducts,Z), opening at one end into suitable pipes, O, of valves, D, having thepins, (Z, the valve- 0, of the air-ducts, b, the valves, D, the stems,

d, connected with said valves, and the diaphragms D, adapted to bepressed outward by the air within the wind-chest, said (Ha phragms beingsuitably connected to the valve-stems; substantially as described.

In witness whereof I have hereunto set my hand, at Chicago, in thecounty of Cook and State of Illinois, this 24th day of April, A. D.1897.

VICTOR ANDERSON.
